Ankr strives to build a resource efficient blockchain framework that truly enables Distributed Cloud Computing (DCC) and provides user-friendly infrastucture for business applications. There are indeed existing cloud solutions, but Ankr is the first one to leverage both blockchain and trusted hardware. Technology Overview Ankr provides a computation-resource-efficient blockchain and an integrated data feed system leveraging both cryptographic primitives and trusted hardware Proof of Useful Work The Proof of Useful Work (PoUW) consensus enables a self-sustainable blockchain framework. Instead of wasting electricity and computing power on hashes like Bitcoin does, PoUW uses these resources towards useful work tasks provided by enterprises and consumers. The protocol runs on SGX-enabled CPUs with remote attestation to ensure security and confidentiality. The novel PoUW approach unlocks the massive potential of idle computing power around the world by providing enough incentives: in this scheme, every computation contributor gets compensated, and some will get the extra reward for generating the blocks. In the future, this mining scheme can promote Universal Basic Income (UBI). Plasma Sidechains The Multi-chain Plasma implementation allows different applications to handle application-specific smart contracts on individual side chains, preventing transactions from overloading the PoUW-based main chain. Native Oracle Service Native Oracle Service (NOS) provides authenticated data feed by leveraging both cryptographic primitives and the trusted execution environment (TEE). Through a standardized API to port data from existing websites, NOS enables simple real-world business adoption
0x is an open protocol that is designed to offer a decentralized exchange as part of the Ethereum blockchain. 0x is made using a protocol that involves Ethereum smart contacts that allow those around the world to run a decentralized exchange. The team behind 0x strongly believes that in the future, you will find thousands of tokens from Ethereum and that 0x can provide an efficient and trustworthy way to exchange them. 0x have several benefits such as it can be any asset. The 0x protocol facilitates the exchange of a growing number of Ethereum-based tokens including currencies, game items, and many more digital assets. Besides, it has a networked liquidity. By sharing a standard API, relayers can easily aggregate liquidity pools, creating network effects around liquidity that compound as more relayers come online. 0x also can be exchanged anywhere. 0x allows trade functionality to fade into the background, enabling developers to focus on building while 0x handles the exchange. The co-founders of 0x are Will Warren and Amir Bandeali, the first of which is the CEO and the second of which is the CTO. Both are in smart contract research and development. Warren used to conduct applied physics research at the Los Alamos National Laboratory after studying mechanical engineering at UC San Diego. Bandeali used to be a fixed income trader with DRW after he studied finance at the University of Illinois, Urbana-Champaign. 0x doesn’t charge fees of any type to use their protocol; it is free. However, if someone chooses to create a decentralized cryptocurrency exchange using the protocol, that person, known as a Relayer, can charge fees. How does it work? 0x protocol works where : A “Creator” sends his request and at that same point the request is posted in an off-chain arrange/order book by the “Relayer”, next to which the request is acknowledged by the “Taker” by pushing the exchange into the task’s DEX smart contract. Thus, the 0x protocol uses off-chain order books, which is maintained by a relayer for settlement of trade between two parties. Relayers, being behind the maintenance and creation of these channels are incentivised by charging and collecting fees. 0x (ZRX) Token: ZRX token is the unique aspect of 0x project which will be used to pay ‘relayers the trading fees by the users of the protocol. It is also a governance token in a decentralized form for the 0x protocol’s upgrade.
